Spring Drum-small painted The Spring or Thunder Drum is the instrument for all those people who say they can't make music! Hold the tube with the spring hanging out of the bottom end, then gently wobble your hand. Try patting your free hand over the open top to produce changes to the sound. Hear the thunder! The noise is amplified just in the same way as a "cup and string" telephone. Price: £5.00 Quantity:
